When I sing Nepali songs it's so easy, but when I try English songs, its hard not with pronounciations n tone but with breathing. I wana learn how to control the breathing while singing. Any Nepali songs with high scale I can do it but English songs with high scale I almost choke myself. 

Lol I took a vocal class and all I learned is how to bark

Be careful not to tear your vocal chords. I think this requires a lot of training or must be born with it i guess. Sometimes i used to wonder whether there was a scorpion biting Mariah Carey's ass when she did those high pitch but later i learnt that she was gifted.
